VALVE.

Specification of Letters Patent.

Patented June 15,1909,

Application filed May 18, 1908. Serial No. 433,403.

To all whom it may concern:

Be it known that I, J onx E. WARD, a eitizen of the United States, and'a resident of the borough of Manhattan, of the city of New York, in thecounty and State of New York,

have invented certain new and useful improvements in Valves, of whichthe following is a specification, reference being had to theaccompanying drawings, forming a part hereof.

' The invention relatesmore particularly to What are known as end trainpipe valves which are employed in the steam. heating apparatus ofrailway cars, although the same may be applied in various otherconnections as will appear hereinafter. In such apparatuses, it isdesirable to provide a valve which shall not permitthe water ofcondensation to collect therein or in the pipe adjacent thereto butthrough which, on the other hand, any such water may readily andautonuttically discharge into the coupling hose connected thereto, thuspreventing the water from cooling and freezing in the train pipe or thevalves at either end thereof. It is also desirable that the steam may beturned on and off by a quarter turn or less of the handle through whichthe valve is manipulated, for the reason that any considerable movementof this handle is'apt to be impeded by adjacent parts and for thefurther reason that a quarter turn or thereabout is easy to effect andoifers at the same time a good indication of the position of the valve,whether-open or closed.

The object of the invention is accordingly to provide a simple andcomparatively inexpensive valvestructure or fitting WlllCll' shall havethe characteristics above referred to and which shall be capable ofbeing contained in a very small com ass.

The invention will be exp ained more fully hereinafter in connectionwith the accompanying drawings in which I Figure 1 is a viewpartly inhorizontal se-:r-

tion and partly in planof a valve embodying the invention, the plane ofthe section. being indicated by the dot and dash line in Fig. 2, whichis a view of the same partly in vertir :11 section and partly inelevation.

The valve is shown in Fig. 2 of the draw ings in the position which itoccupies when screwed in place upon the tram pipe, one such valve beingrovided at each end of a car and forming t e connection between the 1which separates the port a from the port b,

train pipe and the coupling hose by means of which. the pipes uponadjacent cars are gnade to communicate. ln such position, it will soseen that the partition g of the valve,

59 is in line with the bottom of the port a or, what is the same thing,with the bottom of the train pipe which joins the port a. Suchpartition, moreover, overlies the port I) to which the roupling hose isattached; This latter port, as will be seen, forms an obtuse angle, sofar as its direction is concerned, with the other port. In the partition9' are formed one or more passages c, referably a plurality of passages,and such passagesare controlled by a corresponding number of valve plugsi. In this particular instance, there are two passages 0 arranged onopposite sides of the renter of the partition 9 and the valve plugcorresponding with each passage is held against its valve seat in thepartition g by means of a spring h 'which is coiled about a projectionupon the valve plug" which extends upwardly into an arm m formed uponthe valve spindle n, the valve plug thus being free to rotate and movein a vertical direction, but being held down upon its seat through thea-ction. of its spring.

The axis of the spindle is vertical and normal to the plane of thepartition g and the arms or upon the spindle, extending as they do fromthe center outward, bring the valve plug into a position to one side ofthe center line or axis of the spindle; and it will be obvious that thegreater the number of the openings 0 (and therefore of the valve plugs)which are provided, the shorter the arms m may be made withoutdecreasing the area of valve passage. lvloreover, by increasing thenumber of such passages the angularity of the movement of the spindle inorder to open and close the valve may be decreased. It follows thereforethat by previding a plurality of passages through the valve, the fittingembodying the same may be made very compact indeed.

The spindle it extends upward through a suitable opening or recess inthe screw cap and is provided with an enlargement or huh which fits aneniargement 01 the ess in the screw cab, which enlarged rec sufficientlength to constitute a packing chamber or box above the hub, in which apacking 0 is confined between the upper end of the recess, which ispreferably conical as the action of the springs, that oft-thes anr topressure will: servea'lso' o'keep tl-ie spindle drawings) forconveniently 'With. suchua haiiidle it V ow, byjjaiquarter' -turn"ioif'less e opened or closed.

It' bught to be-menf-tioned-that the pipes upon-therailwaycarslto'wlpich the improved valvefis intended to be connected,are gen- .f eralljfinclinedfrom thelcenterto the ends of the cars. j' Inthis wiay, thewater of con dens ation will always'frun down toward the 25 valve where it fshouldfgbe permitted to -dis-' charge into thecoupling hose in order that it maynotkremain in the pipesand freeze or--cau se other injury theneto; v It will be' seen that by reason of thepariular {construction of the applicants device 3. he water passing inby port q/will have a freepassage whenthe valve is open through the portb; which is on a level with the bot tom of theinletpoi't a, and therebeing no partition or other check in the fittingabove I the valve seat.In other words the partition g, is substantially continuous with thebotto n of the pipe and whenthe valve is open, as; is generally the casewhen the ears 40 are coupled together, such partition will not hinderthe water which flows into the, valve from the train pipe from passingdown into the port I) and into the coupling hose. When i the hose isuncoupled, the pressure-of the 4-5 steam in the train pipes will causethe. con- ..dlensedwater in the system to blowuofi' tl'n oughthe blowofi port I) of the valve and throughthe hose. ,Devices of the characterherein set forth f tionable leakage.
